Composition of nanoparticles as carrier for hpv-derived immunogenic fragments

Composition comprising nanoparticles which are loaded with pharmaceutically acceptable compounds comprising one or more human papilloma virus (HPV)-derived immunogenic fragments or a variant thereof, having silicon dioxide and functional groups on the surface, wherein

• the functional groups are capable to carry and/or stabilize both negative and positive charges of the pharmaceutically acceptable compounds,
• the zeta potential of the composition has a value of at least ±15 mV,
• the nanoparticles have a particle size below 150 nm.
